IMPROVEMENT IN FLY-TRAPS.

Specification forming part of Letters Patent No. 139,412, dated May 27,1873; application filed April 26, 1873.

To all whom it may concern:

Be it known that we, ROBERT P. MILLER and WALTER IRWIN MILLER, ofLineville Station, in the county of Crawford 'and State of Pennsylvania,have invented a new and valuable Improvement in Fly Traps; and we dohereby declare that the following is a full, clear, and exactdescription of the construction and operation of the same, referencebeing had to the annexed drawings making a part of this specification,and to the letters and figures of reference marked thereon.

Figure 1 of the drawings is a representation of a side View. Fig. 2 is aplan view. Fig. 3 is a central vertical section View.

This invention has relation to fly-traps and it consists in theconstruction and novel arrangement of the perforated cap, the removablerevolving middle chamber with a passagetube extending upward from itsperforated top, and a lower edge, notched to coincide with the openingsin the inner flange of the base, and cut-ofi' portions to close theseopenings when desired, as hereinafter particularly described.

In the accompanying drawings, the letter A designates the base of thetrap, consisting of a plate having the outer flange a to keep theopenings of the trap shaded from the light, and the inner flange b,through which the said openings 0 are made, at its lowermost portionnext the base-plate. This inner flange b is vertical, and serves toreceive the vertical wall d of the main case B, which is'slipped overit, keeping its place by the friction of the parts when the trap israised. The wall d is notched at e, in its lower edge, to coincide withthe openings 0 of the inner flange b of the base, the wall-spaces nbetween the notches e serving to cut off or shut the openings when thecase B is rotated, so as to bring these wallspaces opposite the openings0. The top I of the case B is convex or conical and perforated. At itsapex is arranged the passage-tube '0, through which the flies crawlseeking the light, after having been attracted within the case B throughthe openings 0 by suitable bait. 1) indicates the cap or reservoir, intowhich the flies pass from the tube c. This cap is perforated to admitthe light as freely as possible, without permitting the escape of theflies. An indented bead, 2, may be made in the wall of the cap toprevent it from being pressed down so far that the tube '0 will beclosed; or an external bead may be formed on the case B for the samepurpose.

What we claim as our invention, and desire to secure by Letters Patent,is-

The fly-trap, consisting of the base A, hav

ing the inner flange b with openings 0, theretating case B having itslower edge notched at e to coincide with the openings 0, its top, thepassage-tube v, and the perforated reservoircap D, constructed andarranged as specified.- In testimony that we claim the above we havehereunto subscribed our names in the presence of two witnesses.
